Drosophilid Flies Research Paper

The Drosophila, also known as the fruit fly, are famous for being ideal in the area of genetic research. The fruit fly has a fairly short life cycle beginning with the female fruit fly laying eggs (typically on fermenting fruit). In only a single day, the fertilized eggs turn into tiny, white, wormlike larva which burrow into the fruit and eat for 4-5 days. The larva then crawls to a dry spot and becomes encased in a pupa where it becomes an adult within another 4-5 days. In just 8-12 short hours after appearing from the pupa case, the female fruit fly can mate and stores enough sperm to fertilize 500 eggs. Their short life cycle is only one of the reasons that they are useful in genetic research. The female lays many eggs that

Dragonfly larvae are main aquatic predators that habitually eat tadpoles and this has strained the tadpoles to come up with devious defence strategies. The tadpoles of leopard frogs will speed up their maturation if they are in a pond with dragonfly larvae. Other species of tadpoles hide or develop ornamentations on their tails to trick the dragonfly larvae into outstanding at less vulnerable parts of their bodies. Dragonfly larvae might be the tigers of the water-weed jungle, but they were not thought to harass (defend, harass, defeat, frighten) adult

Ah summer! The sun is shining, you're stepping out to the back deck with a plate of burgers ready to go on the grill and as you head out the door you've instantly got four flies flicking around your face. Yuck! Flies love the heat of summer which is why they are more in-your-face this time of year. As house flies can spread diseases through the germs they are carrying on their legs, it is important you tackle this pest problem before it becomes the plot of a bad movie. Here are three ways you can beat back these winged insects from your back door.

We began the experiment by dividing into pairs and selecting one mutation of flies. Claire and I started off with Vestigial Flies. We then got our supplies; three clean tubes, three caps, three sponges, fly nap and wand, dissecting microscope, paintbrush, and three small plastic plates (for separation). As a team, Claire began to tap the container containing the mutant flies (this way they stayed at the bottom), while I had my extra sponge and clean tub ready to stick on top of hers’. After counting down to three, she pulled the sponge on her fly container and I quickly placed the empty vial on top. I then flipped the vials upside down and proceeded to knock as many to the empty vial as I could. We did the exact same step as before, counted

Horse Flies are small annoying creatures that grow to be the size of 1 ¼ in. Females primarily feed on blood, yet the male's’ diet is mainly pollen. Small antennas are located on top of their heads. Females have acuminous mouths to extract the blood escaping the exposed wound. Males possess no threat to humans but females are deadly due to their ability to transmit disease by extracting your blood. The information will be divided into three categories disease transmission, Larvae/Adult Diets, and Immune to Pesticide.

The surviving species with the right amount of traits take advantage of these niches and live in them. This is called adaptive radiation. http://evolution.berkeley.edu/evolibrary/news/120901_afterextinction

There is a continuous, uncertain scientific argument among biologists with respect to the speciation of populaces: would they say they are the same species or two separate species? The argument in this paper is, whether the two “Western” Flycatcher populations, Cordilleran population and Pacific slope population are the same species or two separate species.

For more than a century Drosophila Melanogaster has been one of the most intensely studied organisms in biology. Thanks to being sexually dimorphic, having short generation periods, a high fecundity, and only four pairs of chromosomes, Drosophila Melanogaster are exceptional model organisms (Roach et al, 2008). Drosophila Melanogaster broke into the forefront of biological research in the early 20th century, when Dr. Thomas Morgan, using Drosophila, founded contemporary genetics with major discoveries concerning sex-linked inheritance and phylogenetic impact of gene mutation (Metcalfe et al, 2013). Today Drosophila Melanogaster is a staple in classrooms and laboratories alike; serving as not only as an observable means of studying classic Mendelian genetics, but also a model organism for cutting edge medical and scientific research.

The studies in Drosophila melanogaster have helped scientists to have better understand about genetic and scientifically discover the variety of human diseases from mutations. After observing under 50X magnification, the differences between the female and male unknown mutants 651 are that the shape of male’s pseudopupils are larger than female’s and the volume of bristles and hairs on male’s notum are greater than female. In addition, the larva of wild type is a little larger in length and width than the larva of unknown mutant while the color of mutant’s larva is a bit whiter than wild type’s. Most of the distinguish differences of phenotype between wild type and unknown mutant are found on the thoracic notum, which includes the arrangement,

A new mutation in pigmentation of Drosophila melanogaster has been observed called chocolatebar (chbr). This mutation primarily affected the scutum and scutellum of Drosophila melanogaster, causing striations throughout the scutum leading to solid dark pigmentation on the scutellum. The darker pigmentation was primarily focused on the mesothoracic region of the mutated flies, but the wings, head, and abdomen appeared to be darker than the wild-type, (Figure 1) which is responsible for the identification of this mutation as chocolatebar. This mutation affected both male and females, but the expressivity of the phenotype varied slightly between the sexes, as females had more prominent black features, especially on the scutellum, than the males

Centrosome amplification in certain stages of the cell cycle will cause the flies to develop tumorigenesis

The genus drosophila are fruit flies which over years have had various mutations leading to six different eye phenotypes. These eye colors include: wild (not mutated), white, brown, rosy, scarlet, and sepia. The purpose of this experiment is to understand the mutations that occur during gene expression that causes abnormal protein synthesis and produces a mutated phenotype. The experiment will determine the pigments that are present in each of the mutated eye colors

Across the globe, there are many regions that are solely dedicated to produce different types of crops and other produce in order to support the needs and demands of society. Many of these areas are concerned with ways to maximize their crop production, and often many insects, particularly true flies (order Diptera), potentially affect these crops during the growing and harvesting seasons. Dipterans have vastly important roles throughout ecosystems across the world, mainly having the duty of pollinating as well as serving a crucial part of the food chain, allowing many insects and animals a source of food, without having to resort to the ingestion of plants. Many authors have discussed and examined the potential roles that dipterans

Sherwin has produced >300 scientific articles, the more common being related to wood anatomy, as well as >10 books, 4 of them dealing with islands: Island Life (1965), Hawaii: A Natural History (1970), Island Biology (1974) and Tarweeds and Silverswords: Evolution of the Madiinae (Asteraceae) (2003). In island biology (1974), Sherwin demonstrated his encyclopedic knowledge about evolutionary trends and phenomena taking place in both flora and fauna, and the selection pressure which controls them. There are four of Carlquist’s most important contributions to the development of the biology of island

Scientists all across the world have used model organisms to study genetics. These organisms are selected based off of easily noted physical characteristics, their small sizes and relatively short generation time, and also being readily available to use and tractable. That is why Drosophila melanogaster is a great model organisms because it fits all these characteristics. I propose further research on sex-linked eye color mutations in D. melanogaster because studying sex-linked traits will
